Hair Follicle Drug Testing - East Yolo, CA

What it is, How it works

Hair testing is recognized as an effective method for spotting drug and alcohol usage. Hair captures biomarkers in the fibers of growing strands, offering an extended history of alcohol and other drugs. A scalp-near collection can reveal usage up to a three-month period for drugs and alcohol. Collection is straightforward, challenging to tamper, and simple to transport.

A 1.5-inch portion of about 200 hair strands (similar to the size of a #2 pencil) near the scalp equals 100mg, an optimal amount for screening and confirmation. For EtG, additional analyses, and/or screenings exceeding 10 panels, 150mg is advised. We endorse employing a jeweler’s scale for weighing the specimen. If scalp hair isn’t available, a comparable quantity of body hair may be gathered. When we discuss head hair, we mean scalp hair particularly. Body hair pertains to all other hair categories (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result consists of four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a lab’s system. This encompasses ensuring the sample was sealed and dispatched correctly, assigning a LAN (Laboratory Accessioning Number) randomly, and finalizing any other data entry missing from an electronic chain of custody system.

Screening entails a fast preliminary assessment for drugs of abuse. Though Screening is an economical way to exclude drug use for most samples, a positive screen requires confirmation for court acceptability. Samples with a presumptive positive in Screening need secondary verification.

For samples testing presumptively positive during Screening, more hair from the initial specimen is prepped for Extraction. In this phase, drugs are drawn from hair at a substantially lesser concentration than other approaches (such as urine or oral fluid), making hair drug testing the most complex methodology.

Verification of any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as required. The full laboratory procedure from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, compared to the shorter span in urine tests.
• Difficult to deceive: Hair drug tests are challenging to manipulate, enhancing result precision.
• Furnishes historical data: It reveals drug use patterns over time, not solely recent use.

Limitations:

• Cannot spot recent usage: Drugs take about 5-7 days for detectability in hair.
• Expense: Hair drug tests often cost more than other drug detection techniques.
• Result variations: Variables like hair color and personal differences in hair growth affect drug metabolite levels in hair.

Note: Frequently called "hair follicle tests", these examinations assess the hair strand, not the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
